George Zimmerman Has Rare Smile on Second Day of Deliberations

George Zimmerman Has Rare Smile on Second Day of Deliberations (ABC News)

Six Florida women are back inside a jury room for a second day today, pouring over evidence as they deliberate the fate of George Zimmerman, charged with second degree murder and manslaughter for the death of Trayvon Martin.

Zimmerman, whose facial expressons have been emotionless during the trial, appeared to smile in court today as Judge Debra Nelson spoke to the jurors shortly before instructing them to resume deliberations.

Zimmerman , 29, maintains that he shot Martin, 17, in self-defense on Feb. 26, 2012. If convicted of the most serious charge he could be sentenced to life in prison.

His attorneys told ABC News that he is worried about the prospects about possibly spending the rest of his life behind bars or, if acquitted, a life in hiding. He has spent the last few days huddled with family as he awaits the verdict.

The parents of Trayvon Martin have tried to keep a low profile over the last two days. They have spent every day in court listening to attorneys say that their son was either the victim of profiling or the aggressor in an altercation that resulted in his death.

Fulton left the courtroom during the defense's closing argument Friday when Zimmerman's lawyer held up a photo of Martin's dead body for the jury to see.

"Let's face it when you saw those pictures in the court room, you don't want that to be the image of your baby," said Crump. "That's Sybrina's baby boy, and you know the bond between a mother and a son. So she has to cling to the memories of Trayvon when he was growing up and just try to get through. There is no instruction book on how to deal with this."

Crump said Martin's parents plan to be in the courtroom when jurors reach a verdict.

"They're going to be here until the end. They've started this journey over 17 months ago, just asking for simple gestures, and they are [going] to fight for Trayvon to the end so his death won't be in vain," said Crump.

The six women, five of them mothers, who will decide the verdict range in age from their early 30's to their 60's. Four of the women have experience with guns or relatives who own them. Two of them rescue animals. One of the jurors is either Hispanic or black.

The women, who have been sequestered for more than two weeks, will decide one of the more racially charged cases in recent memory.

Friday they asked the court for a list of evidence to review as they decide whether to convict Zimmerman or let him walk free.

Police across Florida are bracing for a verdict. They have created places for people to protest in peace, are monitoring social media and urging people to remain calm.

"As we await this verdict we would like to remind everyone that the city of Sanford is a peaceful location and remains a peaceful location, Sanford Police Chief Cecil Smith said Friday when the case went to the jury. "We have worked…to put together a plan to ensure the safety of Sanford and our surrounding communities."

In Broward County near where Martin lived, police have launched a campaign to encourage people to "be vocal, not violent" and have designated two parks where people can assemble peacefully to express their feelings.
